Abstract. The worldwide demand for roads to serve global economic growth has led to the increasing popularity of road improvement using cement. This, in turn, has led to increased demand for cement and the associated problem of CO 2 emissions. Alkaline-activated materials (AAMs) could be an alternative binder for relatively low strength construction and rehabilitation …

Thus, many of the sand properties chemical and mineralogical compositions …etc. are related to the source rock. However, crushed rock sand differs from the usual river sand in particle shape, grading, surface texture, and particularly in the content of fines or dust. Fines are defined as the part of sand passing a determined test sieve.
